1. A computer system comprising:
- a processor;
a system bus;
an input device;
an output device;
a drive capable of reading data from a substrate configured for rotating access; and
instructions stored in one or more of software, hardware or firmware for controlling said drive to produce rotation of the substrate of sufficient intensity and duration for the purpose of activating a rotation activatable fluid release mechanism of the substrate to render at least a portion of machine readable data stored on the substrate inaccessible or unusable,wherein said instructions include instructions for controlling said drive to produce rotation of the substrate at a speed higher than the normal read speed for said drive to produce activation of the rotation activatable fluid release mechanism.
